If someone does not answer the doorbell when you are selling cookies, but you still think they are home, should you:
a. ring the doorbell again, and again and again
b. leave a note on the door with your phone number so they can contact you later
c. leave them alone and go to the next house
d. ring one more time, if you think they might not have heard you the first time.
C or D. You can decide with your best judgment, but do not bother the people or stay there too long. NEVER leave your contact information with anyone.
